It all started June 11 when a 67-year-old Irrigon man had a late-night rendezvous at the Clover Island Inn with a woman he contacted through an ad she posted on Craigslist. Williams reportedly was staying in the hotel room with his girlfriend, Julie Proper, but he was not there at the time.

After the Irrigon, Ore., man and the prostitute "finished their transaction," the man left the hotel only to run in to Williams outside, court documents said.

Williams "identified himself as a police officer and attempted to handcuff" the man, documents said.

The client resisted, but Williams eventually got him in cuffs, forced him into the man's car and took off driving, court documents said. "Fearing for his life, [the man] jumped out of the car as it was moving," Deputy Prosecutor Scott Johnson wrote in court documents.

The man eventually was flown to a Portland hospital with numerous injuries, including broken bones in his face and road rash.

The prostitute reportedly told police that her boyfriend likely became jealous and assaulted her client.

Williams allegedly helped his girlfriend run an Internet prostitution business.
